Aluminum Uses in the Aerospace Industry

By | Uncategorized | No Comments
Aluminum is widely used in the aerospace industry due to its lightweight, strength, and resistance to corrosion. It has a density of about one-third that of steel, making it a popular choice for aircraft structures where weight is a critical factor.

Here are some of the most common uses of aluminum in aerospace:

  1. Airframes: Aluminum is used extensively in the construction of aircraft structures, including the fuselage, wings, and tail sections. It is an ideal material for airframes because of its strength and durability.
  2. Engine Components: Aluminum is also used in the manufacturing of engine components such as turbine blades, housings, and cylinder heads. Aluminum’s high thermal conductivity and ability to dissipate heat quickly make it an excellent choice for engine components that need to withstand high temperatures.
  3. Fuel Tanks: Aluminum is also used in the construction of fuel tanks for aircraft. Its corrosion resistance properties make it an ideal material for storing and transporting fuel.
  4. Interior Components: Aluminum is used in the manufacture of various interior components such as seating frames, overhead bins, and galley structures. Its lightweight and high strength make it ideal for these applications.

Overall, aluminum has become a crucial material in the aerospace industry due to its unique properties, and it’s expected to continue to play a significant role in future aircraft designs.   Flight Metals stocks various hard to find grades of aluminum including 2014, 7475, and others.
